People fed up with hearing
about an energy crisis talk
about going off the grid.
In the US, the solution is
to install solar panels on
your roof or put up a wind
turbine. But a village in
Germany has taken a different
approach. In the final part
of our three-part series on
biofuels in Europe, Sadie
Babits explains:

The village of Juhnde sits between rolling farmland and woods. The first buildings went up more than a thousand years ago. It looks like a lot of German villages – narrow streets, terra cotta roofs, and a towering church steeple. But talk to anyone here and they’ll tell you Juhnde is no ordinary town. It’s the first community in Germany to be powered and heated by cow manure and grain.

“This is the biogas power station on this side.“

That’s Gerd Paffenholz. He’s lived here in Juhnde for 20 years. He volunteers to show visitors, like me, the village’s bio-energy plant.

“This is the wood heating system and what you don’t see is the network that deliver the hot water in the ground.”

Paffenholz stands on top of an underground storage tank. The liquid manure in here gets pumped over to a massive green tank. That’s the anerobic digester. There, micro-organisms have a hay day eating manure and grains supplied by farmers in Juhnde. The bacteria create biogas, which then gets combusted into heat and electricity. It’s pretty silent outside the power station but open the door…

(engine sound)

That’s the sound of 700 kilowatts of power being generated. The electricity gets sent to the public network. It provides this village of 750 people with renewable power. There’s an added bonus – energy that’s normally lost while making biogas gets captured and is used to heat water. That hot water gets delivered through a series of underground pipes to heat most of the homes in Juhnde.

The village’s bioenergy plant went live five years ago. The price tag? Nearly 8 million dollars. The money came through a government grant and from residents who each ponied up thousands of dollars to join the plant cooperative. The village has also cut its greenhouse gas emissions in half already meeting targets set by the European Union for 2050.

“It shows you what some wise investments and collective thinking can make happen.”

That’s Jim McMillan. He researches biofuels at the National Renewable Energy Laboratory in Boulder, Colorado. He says Juhnde has created an attractive model that could work in the Northern US and Canada where people are more remote and winters are long and hard.

“It’s a good model but Europe, I mean, they’re built out much more than we are and they are doing a lot more in building. They’re density of building, the size of their square foot of their homes are much more right size and so these solutions are easier to implement there than they are here I mean we have a lot more big homes that require a lot more heat.”

Our attitudes are different too. It took several years to get Juhnde’s residents to buy into the idea of going off the grid but now most everyone is on board. Here in the U.S. we’re a lot more individualistic. But McMillan still sees a lot of promise in what Juhnde accomplished.

“So one village is a good example but we need to apply it across the board.”


Other villages in Germany are building bio energy plants. In the U.S. a few towns are attempting parts of Juhnde’s efforts. Reynolds, Indiana replaced the town’s vehicle fleet with cars and trucks that run on bio fuel. It’s now working with a company to turn algae into power. And in Grand Marais, Minnesota, they want to build a central heating system for the town that burns wood chips from the local saw mill.

Farmers are finding they can
make more money selling crops
for energy than for food. A third
of all corn grown in the US gets
turned into ethanol. It’s tough
to balance the need for energy
and food when millions around
the world die from starvation each
year. Still, farmers are reconsidering
their roles – including in Germany.

Farmers are finding they can
make more money selling crops
for energy than for food. A third
of all corn grown in the US gets
turned into ethanol. It’s tough
to balance the need for energy
and food when millions around
the world die from starvation each
year. Still, farmers are reconsidering
their roles – including in Germany.
In the second part of our three-part
series on biofuels in Europe, Sadie
Babits meets with one German
farmer who wants to make the switch
and become an energy farmer:

Erhard Thale jokes a lot about being an organic farmer. It’s about all he can do.

“He has like his corn harvest from two years ago is still lying down on his farm so it’s not sold on the market.”

It’s hard to imagine. We’re outside Ludwigsfelde not too far from Berlin. Thale’s land looks green and healthy – not bad for late fall. But looks can be deceiving. Thale says he’s lost money for the past three years. He blames his land and a volatile world market.

“Then My wife comes and asks, ‘where do we go from here? Piggybank is empty. Money gone.’”

Thale says he can make more money selling his organic corn and rye for energy instead of food. He’s not joking around. There’s a growing movement in Germany to get farmers like Thale to set some of their land aside to grow grains just for energy. There are now areas throughout the country developing so called “bio-energy regions.” The idea is that a community like Ludwigsfelde would produce its energy locally.

Farmers like Thale would sell their grains and manure to a regional bio-energy power plant. Those materials would get turned into green energy. The 20,000 residents who live here wouldn’t have to rely on fossil fuels and they’d cut down on greenhouse gas emissions. Sounds promising. But Thale says he’d build his own plant if he had three million dollars. Then he could keep all the profits from selling energy.

“He needs an uncle in the U.S. with two million euros.” (laughter)

Other farmers, though, are cashing in, finding money in, well, poop.

(sound of milking machine)

A cow chews her cud as an automatic machine does the milking. This milking parlor is part of an agricultural training center here in west central Germany. This is the greenest farm I’ve been on. There’s a bio-energy power plant. Wind turbines and solar arrays.

Klaus Wagner runs the center. He says this cow’s manure is more valuable than the milk.

“That can’t be.”

Wagner sees a growing rivalry between dairy farmers who want to sell milk and those who want to sell manure for biogas.

“I guess that the milk and energy production on the other side belongs together. And those farmers who built 3-4 years ago biogas plant they earn real money now. The biogas plant substitutes the milking production.”

It really comes down to a question of sustainability. How much land here in Germany and, for that matter, the U.S. should be set aside for making energy? It’s not an easy answer. In the long run, if farmers grow grains for energy instead of food, that will impact the food supply and eventually what we pay at the grocery store.
